Image Capture Architecture
To meet the applications of Intelligent Transport Systems (ITS), ITSCAM FF 600 has several functionalities
associated with image acquisition. These features make up a general architecture and can be disabled in
the device setup
Profile
. The image acquisition process begins with the image request (
trigger
). This request
can be made through external sensors, connected to one or more ports of ITSCAM FF 600 (IOs set as
Inputs). In the ports setups it can be informed that the capture trigger will be made by edge (up, down or
both) or level (high and low).
There is an alternative to using external sensors connected to the ITSCAM FF 600
Connection Board
, which
is setting up the Trigger for software activation. In this case, the activation can be in a
Constant
interval of
time or when the equipment identifies movement in the image (
Trigger by Motion
). Choosing
Trigger by
Motion
enables the Motion Detector functionality. The CLASSIFIER is another feature that improves
classifying the vehicles present in the images, it analyzes the images and returns the vehicle type.
After defining the ITSCAM FF 600 image capture flow, the
Multiple Exposures
functionality can be enabled
per request. This technology allows setting up two to eight sequential images, with variation in the capture
parameters at each request.
Identifying the license plate of the vehicles present in the image can be done by enabling the
OCR
functionality, available for several countries. To increase the reading accuracy, the
Majority Voting
can be
enabled.
Motion Detector
The definition of movement between two ITSCAM FF 600 consecutive images depends on the set variation
parameter. In addition to this sensitivity, the ROI (Region of Interest of the Image) in which the movement
will be evaluated can be specified. This region corresponds to a polygon with four vertices, which is drawn
on the image visualization and remains shaded on the visualization. The region definition is displayed after
the
Region of Interest
usage option is enabled.
CLASSIFIER
ITSCAM FF 600 can analyze the captured images in real time and evaluate the images content. This analysis
aims to distinguish motorcycles, cars, trucks, and buses from images that display only the track. This
analysis has a degree of certainty in the classification, considering image samples that were used to
generate this analytical. It is important to inform the correct type of installation, as ITSCAM FF 600 can be
